One tiny flick of a microscopic cellular hair, known as a cilium, can’t do much on its own. But together, these structures routinely pull off biological marvels within the body. Cilia remove inhaled ...

In many cells of the human body, hair-like protrusions known as cilia act as antennae, allowing cells to receive signals from their environment and other cells. As cells grow and divide, each cilium ...

Cilia and flagella are evolutionarily conserved, microtubule-based, hair-like organelles that protrude from the cell surface. They are the fundamental units of motion in cellular biology, and also ...

In recent years, researchers have been learning more about why cellular antennas called cilia are so important. Cilia can act as sensors of the cell's environment and can send and receive signals.

Human bodies have some built-in systems to care for themselves. The cells that line our lungs, nose, brain and reproductive system have cilia, which are tiny, hair-like structures designed to sweep ...

Some see a finger. Others, a worm. Scientists often call it an antenna. This tiny structure, sticking out from the surface of most human cells, is known as the primary cilium. Though nearly every cell ...

Nearly every organism on Earth follows a natural circadian rhythm that is coded by your cell's clock genes, which do exactly as you suspect from the name: regulate your body's rhythm on a 24-hour ...

Existence of cellular structures with specific size raises a fundamental question in biology: How do cells measure length? One conceptual answer to this question is by a molecular ruler, but examples ...

One essential component of each eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells. Cilia and flagella, which are ...

Primary cilia are microscopic sensory antennae that transmit extracellular signals into intracellular biochemical responses. Growing evidence indicates that primary cilia are implicated in brain ...

The rhythmic motions of hair-like cilia move liquids around cells or propel the cells themselves. In nature, cilia flap independently, and mimicking these movements with artificial materials requires ...
